The San Diego Padres made waves at the MLB trade deadline, but they still have one glaring problem that could hold them back.

The Padres announced they’ve optioned JP Sears to Triple-A El Paso. They recalled reliever Sean Reynolds and will go with a nine-man bullpen in the short term. Sears will spend at least 15 days in the minors unless he’s brought up to replace a player going on the injured list.

The whirlwind of activity on the MLB trade market each summer not only sees contenders shore up their rosters for the stretch run, but also leads to a significant shuffling of the prospect landscape.
